affordable
Wasted space
Can survive almost anything.
Save energy and water materials
Size: 10x15 Local Issues: doesn’t mesh well with the culture Materials list: concrete, rebar, Cost: inexpensive Construction path: Construction of an EcoShell begins with a small group of workers pouring a circular floor, to which the Airform is attached 2 inches in from the edge. The Airform is inflated with a small, high-pressure fan, such as fans used for heavy duty vacuum cleaners. After the Airform is inflated, rebar and then concrete are applied over its exterior.
The concrete can be mixed in a bucket or a fabric mixer and hand applied, or it can be mixed with commercial mixers and sprayed in place with Shotcrete equipment. This latter method obviously takes less manpower and at times produces better results. But the former method is also satisfactory and can be completed by inexperienced labourers.
Once the concrete sets, the Airform is removed.
When the EcoShell is to be used for bulk storage, the engineer must calculate the amount of side wall pressure and a corresponding increase in rebar must be added. In addition, there are several products available to add to the concrete mix that reduce cracking and increase concrete quality.
Since the EcoShell is generally not insulated, it won’t be climate controlled, but its concrete does have some thermal value. And it can be covered with thatching, straw or dirt for insulation. Its roof can be coated with aluminized asphalt or a high grade exterior paint, preferably white to reflect heat. Recently we have added a layer of concrete that has polystyrene pellets, or vermiculite, or perlite added to it for insulation. Research: http://www.dftw.org/stories/ecoshell-construction
Sweetwater Bungalows

affordable
Bad with wind
Versatile
Not Lava proof
Attractive
Size: 10x12 Local Issues: would not withstand wind Materials list: wood, glass, laminated polyster-vinyl Cost: $3,800 Construction path:Step 1 illustrates the basic yet solid construction of the side walls and window units. The 4"x 4" corner studs provide the Bungalow with a sturdy foundation. Step 2 shows how the back wall is designed to hold a window. The corner bracing provides lateral support and rigidity to the walls. Step 3 reveals the notched door jambs that keep the door in place. The door has a fully adjustable window with screen for extra ventilation. Step 4 depicts the back and front trusses and the substantial 2"x 6" center ridge. The door and window units are secured to the trusses by the long collar ties. Step 5 describes the fastening of the angle rafters to the trusses and center ridge. Able to carry much more than the Shell and Rain Fly it supports, it provides a dependable bracing against wind and rain. Step 6 shows the Bungalow frame getting its new heavy duty, water- proof skin known as the Shell System. Research: http://www.sweetwaterbungalows.com/
